Briefly stated my improved machine comprises preliminary sets lof paddedpressure or vfeeding rolls and heated ironing rolls oppositely arrangedwith respect to each other and between which the work is fed beforereaching a second battery or gang of padded pressure or feeding rollswhich r0- tate above a reciprocating steam heated ironing chest. When itis desired to give a polish to the work, the preliminary heatedrolls'which have a metallic ironing surface are rotated 'at va greaterrate of speed than the co-operating padded rolls, althoughall of thepreliminary rolls may be rotated at the same rate of speed when aI dullnish is desired. Thefunction ofthe second battery of rolls and steamheated chest is to thoroughly dry the ,work and to set the gloss orpolish on the materials. The reciprocation of the chest furthermoreprevents accumulation of starch and rust and thereby preserves theironing surface of the chest in proper operative condition. Afterpassing the second gang of rollers and the chest, the work is deliveredout through the end of the masuitable brackets are provided also forsupport of the `gears and other parts of the mechanism to be described.The table 4 is provided at the onel end of the machine while thecontainer 5 is provided for receiving the work at the other end. Thepreliminary heated rolls 6, 7 and 8 are rotatably mounted in the framewhile the preliminary padded rolls 9, 10 and 11 are mounted thereabovefor rotation and are supported from the pressure bars 12 which may beraised and lowered with respect to the rest of the -machine Two suchpressure bars are arranged along the sides of the machine. The paddedrolls comprising the second battery are indicated at 13 and are alsosupported by the pressurev bars so as to be raised and lowered withrespect to the chest14 which extends therebelow. The rolls 13, asclearly indicated in Fig. 6, increase in diameter in the direction ofthetravel of the -work through the machine so that the peripheral speed ofeach roll is slightly greater than that of the. preceding roll so as tostretch the work and maintain and deliver the same in flattenedconditionfThe axes of these rolls may or may not be equi-distant fromeach other. The chcst 14 is suitably mounted for reciprocating movementupon the rollers 15 which are engaged by the flanges 16 onvthe bottom ofthe chest and also by the u standing flanges v17 of the angle yironswIln'ch extend along the tinuous chain-.Hof gears.

inwardly extending flanges 18 provided on the top. portions of the framemembers 1 and 2. The padded rolls 9, 10'and 1 1 are y supported from thepressure bars by means of the hangers 2() suspended from the kflanges 21provided on the pressure bars,

the hangers 20 at their other ends receiving the pins 22 extendingthrough ears 23 provided upon the bearings'of the padded rolls. The.springs 24 are also provided within the pressure hars and bear againstthe Abearings of the padded rolls for the purpose of individuallyregulating the pressure of the padded rollsagainst the heated rolls whenin lowered or operative position. Such regulation of the tension ofthese springs is eected by means of screws 25. l/Vhen in loweredposition the pressure bars are free of the weight of the rolls.

- Thedriving mechanism for the padded rolls 9, l() and 11 will now bedescribed. Any suitable source of power may Abe employed for driving thepresent machine and in the present illustration I have shown a drivepulley 30 provided with a clutch mechanism 31 under control of the lever32 which has connection through rod 33, bell crank lever 34, rod 35,bell crank lever 36 to operating lever 37 which is pivoted on thevbracket 38. Thus upon operation of this clutch control mechanism, theshaft 40 can be set in operation and consequently the shaft 41 on theother side of the machine through the bevel gears 42 and 43. The bevelgear 44 carried by the shaft 41 meshes with bevel gear 45 on the stubshaft on which is mounted the Fig. 4, the first padded roll 9 is.operated through the meshing pinions and gears 46., 47, 48, 49, 60, 60,60b and'53, the last gear being on the shaft of the padded roll. Thethird padded roll 11 receives its operation through the meshing gearsand pinions, 46, .47, 48, 54, 55, 56, 57, 58 and 59, the last gear 59being one of the compound gears on the shaft of roll l1. compound geardrives the second padded roll 10 through gear 59a. These gears arearranged in mesh so that the drive for the paddedrolls 9,.-10 and'llisthrough a cony These 'rolls are driven in clock-wise direction.

The other gear of thisA The heated roll 6 receives its operation mountedupon the shaft of the roll 8. These heated rolls are driven incounter-clockwise direction, Fig. 6.`

I Y Another lheated roll 62 is rotatably mounted in the frame of themachine and is driven clock-Wise, Fig. 6, from the pinion 46 through themeshing gears 54,- 55 and 56,

the gear 56 being mounted vupon the shaft of the 'roll 62. Aswill beseen from the drawings, this heated roll is mounted in substantiallyhorizontal alignment with padded rolls 9, 10 and 11. The fourth paddedlroll 63, which is mounted in substantially horizontal alignment withheated rolls 6, 7A and 8, is driven'counter-clockwise, Fig. 6, from oneof gears 74 through gears 74a and 63", the last'named gear being on theshaft of roll 63. The finger guard 37 is connected to the clutchoperating lever 37 so that should the operator try to insert his handbeyond this point in feeding the work, the guard 37a will be actuatedand consequently .the driving clutch of the machine will be thrown out.

Tumbler links 53tl are provided between the shafts of the rolls andthestub shafts of the gears, as clearly illustrated in Figs. 17 and 18,and likewise link 62 between the shaft of heated roll 62 and the shaftof gear 57. Link 60c connects the studs of gears 60 and 60", while link53b is provided between the stub of gear 60b and the shaftl of paddedroll .9. Due to the tumbler arrangement of the gears, the raising of thepressure bars and the rolls will not disturb the mesh of the gears.

The mechanism for operation of the second battery of padded rolls willnow be described. The shaft 40 carries the worm gear 65 which mesheswith gear 66 on the shaft 67. Fixed upon the shaft 67 are the bevelgears 68 and 69 whichmesh with the beveled gears 70 and 7 0a,respectively. Carried by t-he stub shafts of the bevel gears, 70 and 70aare pinions 71 and 72, respectively, each of -which meshes with a pairof gears 73 and 74.

As indicated in Fig. 2, each of the gears 7 3 and l74 meshes with .apair of gears 75 mounted on the shafts of the padded rolls 13 forrotation'thereof. The pressure rolls 13 are supported by means of thehangers 76 suspended from vthe pressure bars and connected at theirlower ends to the ears provided -on the pressure ymember 77 which Ainturn support the shafts of the padded rolls. The depending arms 78 ofthe. pressure members support the'shafts of the driving gears 73 and thelinks 80 are provided between the shafts of the gears 73 and 71 wherebyit is possible for'the pressuremembers to be raised and lowered with thepressure bar and always preserve meshing' `relation between the gears.The degree of pressure of the padded rolls 13 with respect to the chestcan be regulated individually by means of the springs 81 and theadjusting screws 82 therefor. The pressure v arm 85 is connected at oneend to the nects the two links. Thus the padded roll 63 is adapted formovement away from its heated roll upon raising the gang of padded rollsaway from the chest.

The mechanism for raising andlowering the pressure bars will now bedescribed. Fast upon the shaft 40 is the pinion 91 meshing with the gear92 on the shaft 93 upon which is splined the clutch member 94 forclutching engagement with the loosely mounted bevel gear 95. The clutch94 is controlled by means of the lever arm 96, the outer end of which isguided by means of strap 97. Upon throwing in clutch 94, the bevel gear95 drivesthe shaft 97 and also the worm gears 98 and 99 carried thereby.yThe worms 98 and 99 drive the gears 100 and 101, respectively. Thesegears are fixed upon the eccentric shafts 102 and 103, respectively, thee'ccen'trios working in the straps104 and 105, respectively, carried-bythe lower ends of the operating rods 106 and 10.7, respectively. Theserods are connected at their other ends to the pressure bars so as toraise and lower the same upon operation of the driving mechanism vjustnow is thrown in and when the pressure bars .have been brought tothedesiredelevation the clutch will be thrown out. rl`he pressure bars canbe raised to the height desired corresponding to 180o or less rotationof the eccentric. Means are also provided whereby thepressure bars maybe raised by'inanual operation of the hand wheel 110- which is mountedupon shaft 97 for manual operation of the worms 98 and 99 and the othermechanism controlled thereby.' The pressure bars can likewise be4lowered to the proper-,degree according to the degree of llo pressuredesired for the rolls.

The mechanism for reciprocating the steam chest will now be described.Fixed upon the shaft 67 is the worm 115 which meshes with the gear 116fixed upon the shaft 117, carrying gear 118 which in turn meshes with ygear 121 fixed on shaft 120 meshes with gear 121a fixed on' shaft 122.The crank arms 123, fixed upon the shaft 1225at the two ends thereof,have pivotal connection with the rods 124 which are connected at'theirother ends to the depending brackets 125 on the under face of the steamchest. Thus it will be seen that when the machine isset in operation,the steam chest will be given a recipgear'119 on shaft `120. Thed yspeed rocatory motion which designed to be' Vwill move a distance equalat least to that between the axes of the most widely4 spaced adjacentrolls. A felt wiper 126 is suitably Fig. 16,.so as to havewiping-contact with mounted in the frame 126 securedv to the under sideof one of the doier knives'160a the rear portion 127 0f the chest whichdoes not contact with the rollers, so as to prevent' .accumulation ofstarch or rust. A. guide' 167 is secured over this doffer knife forguiding the work and -this doii'er knife is secured in place ingenerally the same manner as the other doier knives 160. The dofferknives prevent the work from sticking tothe lro'lls and will be referredto again.

The heated rolls 6, 7, 8 and 62, as best illustrated in Fig. 7, receivesteam for heating the same through'the inlet pipe 128 and are providedwith a syphon outlet 129 so ar.

ranged as. to 'discharge any condensed steam under pressure of theincomingl live steam. As indicated in Fig. 7, the steam pipe'connectionsextend throu h the gudgeon 131 and a suitable stuffing 0X132 so as topermit the heated rolls t0 rotate in the manner describedwithoutfdisturbing the stationary steam pipe connections therefor.

5d chamber 136 whence it The steam connections for the steam chest arebest illustrated in Figs. 6, 8 and 11.

Steam enters through pipe 135 into chamberV 136 of the joint 135', whichis suitably supported on one of the brace rods 3, and out through pipe137 whence it is delivered through a similar joint 138, thence to pipe139, through another like joint 140,` whence .thesteam enters the chestthrough the pipe connection 141. the steam passes through pipe 142,through the' other' side of joint 140, thence out through pipe143,'through the other side ,of joint 138 and'fnally throughpipe 135 tothe other lside of the' rst joint, through l passes through pipe 137. tothe exhaust.y As' indicated in the drawin s, these steam joints are so-constructe as to permit vthe reciprocatory motion ofl the chest'withoutdisturbing the steam connections. This is madejpossible -bythe swivelconnections at the ointsv'and lsuitable points.

packing means provide at these In order t0 indicate to the -operatorwhether the pressure vbars'are in' ralsed or lowered position, that iswhether thev padded'rolls carried thereby are off or on with respecttothe steam chest, I haveprovided an indicating means automaticallyoperated-by movement-of the pr'essure bars. The indicating dial 150bearmg the marks Upon `leaving the chest,

O and On is fixedly mounted on one a dial so as to move over the face ofthe dial i upon raising and lowering the pressure bar and to indicatethe degreeto which the pressure bars have been .raised or lowered withrespect to the steam chest.

The doffer knives 160, 160% above referred to, prevent the work vfromsticking to the rolls and being carried around with them. These knives(Fig. 24) are metal plates supported upon brackets 161, 161 secured tothe stationary frame. Each knife 160 is held in place by applying thethreaded socket 162a 0f a tool 162. Fig. 23, to each of the twobolts 163extending up through the opposite ends of the doii-er knife from itssupporting brackets 161, the tools thereby serving as clamping nuts forthe knife. To remove said knife, the toolsvare un- Vscrewed from itsbolts and their handle ends 164 are inserted through or into theelongated openings 164a of bails or bridges 165', one on each end of thedoifer knife, to remove it by lifting it from its bolt. Doii'er knife160 differs slightly from knives 160, as shown in Fig. 25, its guidingplate 167 having end fianges through which the securing bolts 163 passand separate slots 1641 in its body for reception ofthe by utilizing thepower of themachine.

This is accomplished by loosening the outside end lof the padding whichis preferably 'muslin or thev like, and upon dlsengaging the individualclutch 170 of the particular roll, the padding material can', be unwound4from the roll which is then' free to rotate independently. of itsdriving connection. Then upon replacing the old padding with the newmaterial, the one end ofthe material is suitably attached to the core ofthe :roll and .the .individual clutch is then thrown in and the power.turned on so as to wind the new material on tothe roll to the extentdesired. The machine is then stopped and the outer end of lthe padding`lmay vbe secured in any suitable manner, it lbeing preferablefhowever,to depend u 0n coto prevent any wrinkling vof the padding hesion of thematerial for securing t le' samev handle end of the tools 162 forremoving it.

which might result should the outer end be positively fastened. For thispurpose, each padded roll Vis provided with .such a clutch 170 forthrowing the roll into and out of driving connection with the' drivinggear freely mounted :upon the shaft of the roll.

' The operation is briefly stated as follows. When ironing a collar forinstance, it is laid fiat with the outer face of the Hap and the innerface of the band down so as to enga e the preliminary heated rolls as itis feg into the machine. The relatively reat s d of the heatedrollsgives a polis or g oss to the .faces exposed thereto. As the collarthen passes between the rolls 62 and 63,'the inner face of the ap andthe outer face of the band are ironed as they pass over the metallicironing surface of' the `heated roll 63. Thus the collar which has nowbeen ironed and polished is fed between the ironing chest and paddedrolls to be thoroughly dried and to have the polish set. For a domesticfinish, the operation is the same V.except that all the rolls are drivenat the same speed so as to omit the olish.

Heretofore, thel inner face of the ap of a collar has been ironed firstand the gloss given to its outer face later, that is after the .collarhas becomel practically dry. f With my machine however the polish isgiven to the outer ace of the flap before being thoroughly dried andconsequently better, results are obtained.

.. Other advantages flowing from Athis in'- vention will be apparent tothose who are familiar with the art to which it relates.
